Scott McLaughlin has laid down the law with a record-breaking lap around Mount Panorama in Practice 3.
The timesheets came to life at the end of the first day of running at the Bathurst 1000, as teams prepare for Friday's qualifying.
McLaughlin shot to the top in the second half of the hour-long session with a 2:04.2835s lap to close to within four tenths of his own Mount Panorama record.
He then upped the ante to better his own 2:03.831s lap record from the 2017 Top 10 Shootout, posting a 2:03.7728s flyer.
The team came despite only running greens on the right-side of the car.
It registered an improvement of nine tenths on the quickest time from earlier in the day, set by Jamie Whincup in Practice 1.
Whincup was second quickest, less than two tenths behind championship leader McLaughlin.
The Tickford Racing Mustangs of Cameron Waters and Will Davison also snuck under the 2:04s barrier. Chaz Mostert, Lee Holdsworth and Fabian Coulthard made it six Fords in the top seven, with Shane van Gisbergen, Anton De Pasquale and Rick Kelly completing the top 10.
Following a crash-filled co-driver only session, Practice 3 was much cleaner with no major accidents to speak of.
Walkinshaw Andretti United's James Courtney had a number of moments but escaped with no more than some worn tyres and a bumper full of gravel.
Nick Percat was among others to have a minor off.
Only 24 cars took to the track, with the Kostecki Brothers Racing wildcard and the Penrite Racing Holden of David Reynolds/Luke Youlden both requiring repairs following crashes in Practice 2.
Two more practice sessions, starting 8:25am and 11:05am tomorrow, will precede qualifying, with a spot in the Top 10 Shootout up for grabs.
